Application filed December 15, 1913. Serial No. 806,748. 7

To all whom it may concern Be it known that I, DENIS MAoHnLn HOL- LINS,a subject of King George V of Great Britain, residing at Blackburn, 1nthecounty of Lancaster, England, have invented certain new and usefulImprovements 111 or Connected with the Take-Up Motions of Looms forWeaving, of which the following is a specification.

This invention relates to loomtake-up motions and particularly to thepositive worm driven take-up motions which'are employed in looms forweaving fustian or velvet or like fabrics,and the object of my inventionis to provide means for automatically stopping the take-up immediatelythe weft fork motion operates on breakage or absence of weft, or on theactuation of the weft replenishing mechanism when weft exhaustion isdetected by a filling feeler, in order that the next pick inserted aftera change has been made may be beaten up close against the last pick, itbeing advantageous 1n weaving fustian or velvet to have the picks ofweft closely laid adiacent each other.

My invention, and the manner in which 1t is carried into practice, willbe descr1bed with reference to the accompanying drawing; in which Figure1 is a front elevation of so much of a positive worm driven take-upmotion as is necessary for thepurpose of enabling the improvements tobeunderstoodzowhile Fig. 2 is a section on theline AA,Fi2. 1, looking inthe direction of the arrow B, certain of the parts shown in Fig. 1 beingomitted from this figure. i

Referring tothe drawing, 1 represents the sand beam or roll, and '2 thecloth'beam or roll. Fast on the shaft of the sand roll is a spur wheel 3which meshes with a pinion 4: integral with or secured on the axis of aworm wheel 5. This worm wheel meshes with a worm 6-fast on a shaft-7'onthefront end of which is loosely mounted a spur wheel 8, to whichmotion is transmitted through spur gears 9, 10 and 11 from the tappetshaft of the loom. The above parts and, their arrangement" with means toclutch the gear 8 to the shaft 7', constitute an ordinary form ofworm-driven take-up motion and do not in themselves form a part of myinventiomwhich consists in providing means wherebyithef gear '8 isunclutchei'l from "the" shaft 7""im'm'ediately the weft fork motionoperates on breakage or absence of weft or, if a weft feeler mechanismbe employed, in case such mechanism detects substantial weftexhaustion.-

In carrying out my invention as applied in connection with a weft forkmotion, I

mount loosely on the usual stop or change of weft. The boss 13 of thelever 13 is provided with a short extension or arm 13 carryinga pin, lugor the like 14 which extends in the path of and is adapted to engage theupper end 15' of a lever 15 pivotally mounted on a stud 16 carried by asuitable fixed bracket 17. The lower end or arm 15 of the lever 15 isformed or provided with a circular portion or ring 15 which is adaptedto pass'over, and occupy a position concentric with, a boss 8 on thespur wheel 8.

7 On the'outer or forward end of the shaft 7 is'secured' an arm 18carrying at its outer end a stud 19 Which is adapted to move freelythrough an opening in the arm. Near the inner end of the stud 19 is aflange,

collar, or 'thelike "20, which is normallv held in engagement or contactwith the face of th'e boss 8 and with the face of the circular portionor'ring 15 of the lever 15 by means of a" spring 21' confined on thestud 19 between the flange or collar 20 and the arm 18.

In the boss 8 of the wheel 8 I form a number of radial slotsor'rec'esses 8 into one or other of which the inner end 19' of thestud19 is adapted to enter; the engagement of the said stud with one ofthe said recesses looking or clutching the spur wheel 8 to the shaft'7Von whichit is mounted. so that the breakageofweft, the movement oftheweft fork'slide in the ordinary manner to rock roll I is immediatelythe stopor change rod 12, rocks the lever 13 and causes the arm orextension 13 of the arm 13 to be moved inwardly or toward the lever 15.This movement of the arm 13 .throughthe pin or lug l e-thereon, causesthe upper end of the lever 15 to be forced inwardly or in the directionof the arrow 0, Fig. 2, and the lower end 15 of said lever to be movedoutwardly or in the opposite direction as indicated by the arrow 1),Fig. 1.

The engagement of the circular portion .or ring 15 ofthe lever 15 withthe collar or flange 20' causes the stud 19 to be forced outwardly,against the action of the spring 2l',and its inner end 19 to be movedclear of the opening or recess 8 in which it happenedto be engaged. v 7

The wheel 8 is thereupon permitted to rotate idly upon the shaft 7 whichthus ceases to be driven, so that the motion of the sand arrested andthe takeup ceases. 1 7 7 7 Onnormal conditions being reestablished andthe weft fork slide moving back to normal position, .thecircular'portion or ring 15 -is released and the stud 19 isforced backagainst the face of the boss 8. The wheel 8 being constantly driven, theinner end of the stud 19 isforced into the first opening or recess 8-which is presented opposite thereto, and the wheel 8 is again locked tothe worm shaft 7 to cause motion to be transmitted to the sand fabric. vI v The spring-actuated stud 19 is provided on its outer end with a knobor device 19 to enable it to be drawn outwardly by hand to free it fromthe boss 8 of the wheel 8, and when thus drawn out it serves as a handleto the arm '18 and enables the operative to rotatetheworm shaft 7forwardly or backwardly at will to windi-up or let back.

the fabric. v

The pin 14: may be carried by an extension on the boss of the usualfixed arm 22 instead'of being carried by an extension on a separate armloosely mounted on the stop or change rod as shown.

The construction and arrangement ofthe parts may be varied withoutdeparting from my invention. :Ifthe improvements are appliedinconjunctionwith' a Weft feeler motion,-the lever 15 maybe arranged tobe' bination of a shaft, a sand or take-up roll,

means for driving the latter from the forrollto take up the other ofsaid openings or recesses, said pin being provided with a flange orcollar, a

lever having a portion underlying said flange or collar, and means torock saidlever to disengage the pin from said openings or recess whenfilling is absent or substantially exhausted.

r 2. In a loom take-up motion, the combina .tion with a shaft carrying aworm by which 'Inotion'is transmitted to the sand roll and a driven spurwheel loosely mounted on said shaft, of an arm fast on said shaft, aspring'actuated stud carried by said arm, a boss on said spur wheelhaving in its face a series of radial openings or recesses in one orother-of which the inner end of the spring actuated stud is adapted toengage, a pivoted lever having a circular portion: or ring encircling orconcentric with the said boss,

a flange, collar or the like on the stud adapt-' ed to be engaged bysaid ring or circular portion, and means to cause said lever to berocked, on indication by the weft forkn1otion of breakage or absence ofWeft, or on indication by the weft feeler motion'of'weft exhaustion.

3. In a take-up motion for looms, thecom- V bination of a pinion or spurWheel continuously operated by a going part of the loom, a takeup, meansfor transmitting motion from said pinion or spur wheel to the takeupincluding a shaft, an arm carried by said shaft and having a pin foroperatively'engaging the pinion or spur wheel andsaid shaft, a fiangeorcollar mounted on said pin, a leverhavinga part underlying saidflange-or collar and bearing upon a face of the pinion spur wheel, andmeans for causing saidlever tomove the pin and interrupt theoperative'relation between the shaft-and pinion or spur upon detectionof filling absence or substantial exhaustion.

4- In a take-up motion for looms, the com bination of a shaft, a take-upor sand roll, means for driving the latter from the former, said meansincluding av continuously driven pinion or spur wheel, a" combinedmanually and automatically controlled pin device for operativelyconnecting and disconnecting the shaft and pinion or spur wheel andhaving a hand engaging head and a flange or collar, a lever having abearing portion on .which said flange or collar travels, and means foractuating the lever to automatically disengage the operativeconnectionsbetween the pin and pinion or spur wheel upon detection offilling absence or substantial exhaustion.

5. In a take-up motion for looms, the combination of ashaft, a wormfixed thereto, a take-up or; sand roll, operating con- 10 rests, andmeans for tilting the lever to disengage the pin from the openings orrecesses upon absence or substantial exhaustion of filling. 1
